I use this system and it's amazing!

We had an exterminator several years ago give us that advice. Don't kill on contact, but rather put the stuff down that they then get all over their bodies and bring it back to the nest and spread it around to their colony-mates. In that instance, the exterminator couldn't find any sort of nest in the house, but outside, about 30 feet from the house, was a decaying tree and it was completely infested with the big carpenter ants. He sprayed around the foundation with some sort of ant poison and voila! No more ants!
